Public Viewing Events

Summer 2019 Public Nights
Wednesday, July 17 @ 9:00 pm
DMF Science and Mathematics Center Observing Decks
24 Park Ave.
02325 Bridgewater , MA
United States
Massachusetts US

Weather-Dependent: During public nights, the observatory's viewing patios are open with multiple telescopes for you to look through, and a staff of astronomy enthusiasts ready to talk astronomy!  This summer, the planets Jupiter and Saturn will be the stars of our show along with the Ring Nebula and lovely globular cluster M13. Be sure to check our weather announcement before making the trip.  You may park in the West Campus Lot. Dates and times for Summer 2019 are:

- July 17, 20 and 31 from 9:00 - 10:30 pm

- August 14 and 17 from 8:30 - 10:00 pm

Call our hotline at 508-531-DARK a few hours before all events to check whether we will be open (or follow us on Twitter @BSUObservatory, or check our Facebook page).  You may park in the West Campus Lot behind the Science and Mathematics Center.  Use any entrance and make your way to the building's central lobby.  There, you will find elevators and stairs to take you to the 5th floor observing decks.

  • If using the elevator: Use the right-hand elevator to go all the way to floor 5.
  • If taking the stairs: Go all the way up the main staircase to the 4th floor, then turn right and right again.  Enter the first door on your right (it's red).   The staircase behind that door takes you to the 5th floor.

Observatory outreach sessions are free, appropriate for all ages, and made possible by the support of BSU's Physics department as well as CASE, the Dean's Office, Provost's Office, Office of External Affairs and the Office of Academic Affairs.  Please visit our Outreach Program page to learn more about our outreach program.  Please visit the CASE website to learn more about other STEM outreach opportunities.

If you require any special accommodations, please call the observatory manager at 508-531-2093 as far in advance of your visit as possible so we can meet your needs!

If you wish, you can print out a parking pass--this is not necessary during our event times, but would prevent ticketing outside those times.  Visit the Parking Service Website to print a pass.

Three of our students have built a 17-inch dobsonian telescope that we can use on our decks.  This telescope is more powerful than the one in the dome!
